Abstract (en)
[origin: ES486925A1] Hardeners for polyepoxides containing more than one, 1,2-epoxide group per molecule comprising a cyanoethylated polyamide amine containing free secondary or primary or secondary and primary amino groups, said cyanoethylated poly-amide amine is a reaction product of polyadded units of (A) 1 mole of a polyamine corresponding to the formula: < IMAGE > in which p=0, n=2 or 3, m=0 to 6 and X=NH2, or p=1, n=2 or 3, m=0 and X=H, (B) from 0.5 to 2.3 moles of a saturated lactam, and (C) from 0.4 to 2.8 moles of acrylonitrile, methacrylonitrile or mixtures thereof. The hardener may be additionally modified with from 0.01 to 1.8 moles of a 1,2-alkylene oxide containing from 2 to 4 carbon atoms or with from 0.001 to 0.3 moles of a carboxylic acid or with the 1,2-alkylene oxide and the carboxylic acid in the quantities indicated, based in each case on 1 mole of the polyamine. The hardeners harden with 1,2-polyepoxides even in thin layers, over a period of 24 hours at room temperature to form clear, smooth films having a non-tacky fault-free surface.
